8.8.12 Batch
When Batch mode is active, a start signal on terminals 24 and 21 (
7.2.2 'Electrical installation' on page 49 ) triggers dosing until a previously defined
quantity (see
concentration (
Connect the zero-potential contact to the corresponding input and GND.
– Do not connect any external voltages.
– Zero-potential contact (relay)
– max. external voltage: 230 V, AC/DC, max. 3 A.
– Reserve signal: Contact closed/opened approx. 500 ms
In batch mode, the pump always runs with 100% metering capacity.
Batch metering can be interrupted by deactivating the dosing release or by switching off
the pump.
NOTICE!
The [Batch] function takes priority over all other operating modes.
When the [Batch] is activated, pulses stored in the [Pulse] operating mode are
deleted for safety reasons.
Ä '[Set Batch] - [Initial batch]' on page 111 ) or the corresponding
Ä '[Set Batch] - [ Batch concentration]' on page 112 ) is reached.
As long as the contact is in the closed position (1), the initial batch is repeated. The initial
batch can be interrupted by removing the dosing release or the alarm at a low fill level. If
the dosing release or the alarm at a low fill level is triggered again, the initial metering is
continued.
This differs from pulse mode, where the pump responds once to a rising signal.
